IMPROVEMENT IN OXVHVDROGEN BURNERS.

Specification forming part of Letters Patent No. 123,537, dated February6, 1872.

To all whom it may concern:

Be it known that I, Asa W. WILKINSON, of the city, county, and State ofNew York, have invented a new and useful Improvement in OxyhydrogenBurners; and I do hereby declare the following to be a full, clear, andexact description thereof, which will enable those skilled in the art tomake and use the same, reference being had to the accompanyin g drawingforming part of this specification, in which drawing- Figure 1represents a longitudinal central section of my invention. Fig. 2 is atransverse section of the same in the plane 0001;, Fig. 1. Fig. ,3 is asimilar section in the plane 3/ 3 Fig. l.

bimilar letters indicate corresponding parts.

This invention consists in the arrangement of two chambers, one of whichcommunicates with the hydrogen-supply pipe and the other with theoxygen-supply pipe, in combination with a compound nozzle, made of anexternal tube, which screws on a nipple formed on the hydrogen-chamber,and of an internal tube, which screws in a socket communicating with theoxygen-chamber, and which extends up through the center of the externaltube in such a manner that the oxygen is not permitted to mingle withthe hydrogen until it reaches the point of combustion, thereby avoidingall danger of an explosion and at the same time the burner can bereadily taken apart for the purpose of cleaning; or, if desired,different sized tubes can be inserted to bring the quantity of oxygencarried to the point of combus tion in the proper relation to thequantity and quality of the combustible gas.

In the drawing, the letter A designates my burner, in the body of whichare formed two chambers, to b, one of which connects with a pipe, B,through which oxygen is supplied, while the other connnunicates with apipe, 0, which supplies a combustible gas, such as hydrogen orcarbureted hydrogen. These two chambers are formed in the same piece ofcasting, and they communicate with each other through a channel, 0,which is provided with an internal screw-thread to receive a small tube,d, and, if this tube is secured in position, he direct communicationbetween the chamburs a and b is cut 011'. The tube (1 extends throughthe center of the hydrogen-chamber b and through a'tube, e, which isscrewed on a nipple, f, tormedat the end of said hydroing.

gen-chamber, as shown in Fig. l of the draw- By these means a compoundnozzle is formed composed of the inner oxygen-tube d and the outerhydrogen-tube e,- and, if both the pipes B and O are opened, the gasesadmitted through them are not permitted to mingle with each other untilthey have reached the point of combustion 5 and since the oxygen-tube clextends up through the center of the hydrogentube, the oxygendischarging from said tube cl is caused to mingle intimately with thecombustible gas discharging from the tube 6, and a complete combustionis effected. Furthermore, the oxygen is not mixed with the combustiblegas until it reaches the point of conr bustion, and consequently alldanger of an explosion is avoided.

The tubes d and 0 can easily be removed for the purpose of cleaning; orthey can be changed for others of a larger or smaller capacity,according to the quality of the two gases, and particularly of thecombustible gas and if only one gas is to be used, the tube cl inay beentirely removed, so that a burner is obtained which is cheap and simplein construction, free from all danger, and capable of being used forgases of different nature or quality, separately or combined.

I do not broadly claim a burner connected with oxygen and hydrogen pipesin such a manner that the oxygen is prevented from mingling with thehydrogen until it reaches the point of combustion, as such is not new 5but What I claim as new, and desire to secure by Letters Patent, is

A burner constructed and operating as herein shown and described, thebody of which is composed of a single piece of casting provided with twochambers, one of which connects with the hydrogen-supply pipe and withthe hydrogen-discharge pipe, while the other c011- nects with theoxygen-supply pipe and with the oxygen-discharge pipe, the latterextending up through the center of the hydrogendischa-rge pipe, all thepipes being secured to the casting, which forms the body of the burner,by means of screw-threads, as and for the purpose set forth.
